REFERENCE TO RELATED APPLICATIONS

This patent application claims priority to U.S. Provisional Patent Application No. 62/882,667 filed Aug. 5, 2019 and is entitled “DOCK FOR SURGICAL EQUIPMENT HOLDER.” The entire 62/882,667 application is hereby incorporated by reference in their entirety.

FIELD

The claimed invention relates to surgical devices, and more specifically to a dock for surgical equipment holders.

BACKGROUND

Laparoscopic, endoscopic, and other types of minimally invasive surgical procedures often rely on percutaneous introduction of surgical instruments into an internal region of a patient where the surgical procedure is to be performed. Surgeons continue to find it desirable to utilize smaller and smaller access incisions in order to minimize trauma and reduce patient recovery times. Frequently, surgeons will make additional small incisions through which a viewing scope or other surgical equipment may be passed to assist in the operation. In the case of viewing scopes, an assistant may manipulate and/or hold the scope in a fixed position for the surgeon so that the surgeon may look at images, acquired by the scope, on a monitor screen in order to perform the minimally invasive operation. Equipment holders may be used in lieu of an assistant to position and hold surgical equipment such as, but not limited to, a viewing scope.

While surgical equipment holders are known to those skilled in the art, surgical equipment holders or docks for surgical equipment holders having the capability of mounting several, articulatable surgical equipment holders is desirable. The ability to adjust one or more surgical devices over multiple degrees of freedom may facilitate the use of multiple surgical devices including endoscopes, retractors, and the like, which are adjustable and mountable within an operating field on or around a surgical operating table, for example, on the rail of a surgical table or some other equipment in an operating room.

Other industries are also beset with the similar dilemma of having the capability to easily, reliably and adjustably mount one or more instruments or instrumentation holders. While instrumentation holders are known to those skilled in the art, easily adjustable mounts with enhanced mechanical function are not as prevalent. Therefore, it would be desirable to have a single docking station for adjustably mounting multiple surgical equipment holders.

DETAILED DESCRIPTION

FIG. 1 is a top-right-front perspective view of one embodiment of a surgical equipment holder dock. This embodiment of a surgical equipment holder dock 10 includes a base 12 which defines a pair of lower clamp jaws 14, a lower stop 20, and an upper stop 22. Internally movable within the base 12 of the surgical equipment holder dock 10 is an upper clamp jaw 16 connected to an upper clamp jaw shaft 18. The upper clamp jaw shaft 18 includes a stop pin 24 which is located on the upper clamp jaw shaft 18 such that the pin 24 is located between the lower stop 20 and the upper stop 22 and is configured to limit the vertical travel of the upper clamp jaw shaft 18 and therefore the relative position of the upper clamp jaw 16 in relation to the lower clamp jaws 14. Other embodiments may or may not include stop pins and may limit travel of the movable portion of the clamp jaws by means known to those skilled in the arts. Other embodiments may not limit travel at all. Other embodiments may have a movable lower clamp jaws or movable lower and upper clamp jaws. Other embodiments may have additional features on the inside portions or surfaces of the upper or lower clamp jaws, such as bevels or other textured features configured to improve consistent clamping forces to accommodate a variety of surgical rail shapes and sizes. The base 12 is configured to clamp the surgical equipment holder dock 10 to a surgical table rail. Attached to the upper portion of the base 12 is a central docking arm 26. This central docking arm 26 has a locking nut 28 attached to the top of the central docking arm 26. Above the locking nut 28 is a body lock knob 30, which is connected to the upper clamp jaw shaft 18 via an inner shaft or inner rod, which is not explicitly shown in this view, but will be discussed later. Above the body lock knob 30 is a central ball cup or socket, also not shown in this view but will be discussed later. A central attachment nut 32 is coupled to the socket. The attachment nut 32 includes two lower extendable moment arms 34 and two upper extendable moment arms 36. A large coupler ball 38 is held between the socket attached to the central docking arm 26 and the attachment nut 32. A bent coupler rod 40 is attached on one end to the large coupler ball 38 and attached to a small coupler ball 42 on the opposite end. Over the small coupler ball 42, a retainer ring 44 is connected, which will later serve as a mounting point for a surgical equipment holder, which is not shown in this view. In addition to the central docking arm 26, the surgical equipment holder dock 10 also has a first side docking arm 46 and a second side docking arm 64 attached to the base 12, each angled at an approximate angle of 45 degrees and in the same plane relative to the central docking arm 26. While a 45-degree angle is shown in this embodiments, other embodiments may have other angles of the side arm as compared to the central docking arm, as well as side arms not in the same plane as the central docking arm. The first side docking arm 46 defines a first side coupling ball cup 48, not visible in this view, which is configured to combine with a first side attachment nut 50 having two lower extendable moment arms 52 and two upper extendable moment arm 54. A large coupler ball 56 is held between the coupling ball cup 48 and the attachment nut 50. A bent coupler rod 58 is attached on one end to the large coupler ball 56 and attached to a small coupler ball 60 on the opposite end. Over the small coupler ball 60, a retainer ring 62 is connected, which will later serve as a mounting point for a surgical equipment holder, which is not shown in this view. The second side docking arm 64 also defines a second side coupling ball cup 66 which is configured to combine with a second side attachment nut 68 having two lower extendable moment arms 70 and two upper extendable moment arms 72. A large coupler ball 74 is held between the coupling ball cup 66 and the attachment nut 68. A bent coupler rod 76 is attached on one end to the large coupler ball 74 and attached to a small coupler ball 78 on the opposite end of the coupler rod 76. Over the small coupler ball 78, a retainer ring 80 is connected, which will later serve as a mounting point for a surgical equipment holder which is not shown in this view. The position of each of the coupler rods 40, 58, 76 can be positioned and locked by first loosening one of the attachment nuts 32, 50, 68 placing the position of the coupler rod 40, 58, 76 as desired, and therefore any attached fixturing or devices, such as surgical equipment holders. Next, the attachment nut 32, 50, 68 is tightened, thereby locking the coupler rod 40, 58, 76 into the desired position by clamping the large coupler ball 38, 56, 74 between the attachment nut 32, 50, 68 and each ball cup 128, 48, 66. An attachment nut may also be referred to as an attachment socket.

FIGS. 2A-2E are a series of exploded views illustrating the assembly steps of the surgical equipment dock of FIG. 1. FIG. 2A shows the base 12 which defines the lower clamp jaws 14, the lower stop 20, and the upper stop 22. There is also a hole 108 near the top of the base 12 for the insertion of a stop pin 24. The base is configured to slidably receive the upper clamp jaw shaft 18 which defines the upper clamp jaw 16. This upper jaw 16 is movable relative to the lower clamp jaws 14 on the base 12 and can be tightened onto a variety of surgical table rails or fixed to other structures. The upper clamp jaw shaft 18 also has a hole 90 configured to receive a stop pin 24 and a hole 92 configured to receive the shaft step 134 of the inner shaft 130. The base 12 also defines a center arm mount hole 82 and two side arm mounts 84, 88. The two side arm mounts 84, 88 have threads 86 for attaching side arms to the base 12.

Next, a hollow outer shaft 98 is inserted through a hole 110 in the locking nut 28 and fixedly attached to the base 12 by inserting the shaft step 106 portion of the outer shaft 98 first into the center arm mount hole 82 on the base 12. The locking nut 28 is held captive on the outer shaft 98 since the diameter of the step 112 inside the locking nut 28 is sized and configured to mate with and be smaller diameter than the step 100 on the upper end of the outer shaft 98. The shaft step 106 is fitted into center arm mount hole 82 on the base 12. This can be attached by welding, adhesion, or other methods known in the arts. The outer shaft 98 also has several lateral openings 104 configured to enable cleaning and/or sterilization procedures to reach the insides of the central docking arm 26. The central docking arm 26 also has a central hole 102 configured to receive the inner shaft 130. The threads 114 on the locking nut 28 mate with the outer threads 126 on the body lock knob 30 on either side of the step 100 on the outer shaft 98. The inner shaft 130 is then inserted into center hole 124 of inner shaft 130, through the central hole 102 of the outer shaft 98, and into center arm mount hole 82 of base 12 to be fixedly attached to upper clamp jaw shaft 18. The shaft step 134 on the inner shaft 130 mates with the hole 92 of the upper clamp jaw shaft 18. Once the inner shaft 130 is inserted through the outer shaft 98, the hollow outer rod or outer shaft 98 is disposed over the inner shaft 130 or rod and the inner shaft 130 is free to rotate within the outer shaft 98. The body lock knob 30 defines inner threads 122 inside the center hole 124 as well as outer threads 126 on the underside of the body lock knob 30. The body lock knob 30 also defines several recesses 118 and protrusions 120 to form an ergonomic gripping surface for handling the body lock knob 30.

The inner shaft 130 also defines a central ball cup 128 towards the upper portion. The ball cup 128 further defines an outer recess wall 146 and an inner recess wall 138. The outer surface of the inner recess wall 138 has threads 142 and there is a socket recess 148 defined by the space between the outer recess wall 146 and the inner recess wall 138. The threads 142 and socket recess 148 are configured for accepting an attachment nut, which is not shown here, but will be discussed later. The inner recess wall 138 further defines several knurls 140 on the top edge, configured to aid in gripping a large coupler ball 38, shown later, as well as a central ball recess 144. In operation, the upper threads 132 of inner shaft 130 and inner threads 122 on the body lock knob 30 enmesh and when the body lock knob 30 is rotated clockwise, the upper threads 132 drive the inner shaft 130 in a downward direction, thereby moving the upper clamp jaw 16 closer to the lower clamp jaws 14 and closing or tightening the lower clamp jaws 14 and upper clamp jaw 16 together. When the body lock knob 30 is rotated counterclockwise, the upper threads 132 drive the inner shaft 130 in an upward direction, thereby moving the upper clamp jaw 16 further away from the lower clamp jaws 14 and loosening the lower clamp jaws 14 and upper clamp jaw 16 apart from one another. Once the relative positions of the lower clamp jaws 14 and upper clamp jaw 16 is obtained and sufficient clamping force is achieved, the threads 114 on locking nut 28 and the outer threads 126 on body lock knob 30 are tightened to lock the position of the lower clamp jaws 14 and upper clamp jaw 16 in the desired position when clamped to a surgical table rail or other structure. Other embodiments may have alternate tightening mechanisms or have the body lock clamp configured to rotate counterclockwise to tighten and clockwise to loosen.

FIG. 2B is an exploded view of a portion of the assembly of the surgical equipment holder dock 10 of FIG. 1, focusing on an attachment nut 68, also known as an attachment nut. The attachment nut 68 has a generally disc-shaped structure. The top layer 160, mid layer 162, and bottom layer 164 are flat, thin segments defined by the attachment nut 68 that extend outward from the center structure of the attachment nut 68. The attachment nut 68, including the top layer 160, mid layer 162, and bottom layer 164 further define several recesses 150 and protrusions 152 encircling the circumference of the attachment nut 68. These recesses 150 and protrusions 152 form an ergonomic gripping feature on the overall form of the attachment nut 68, which may enable or facilitate hand tightening of the attachment nut 68 by providing gripping features. The attachment nut 68 also defines a bevel 154 which permits clearance for any attachments to be positioned at greater angles and with increased clearance. The spacing between the top layer 160, mid layer 162, and bottom layer 164 define an upper slot 166 and a lower slot 168. The mid layer 162 and bottom layer 164 define several holes 170. An upper extendable moment arm 72 and a lower extendable moment arm 70, each having a mounting hole 176, 178 are placed in the upper slot 166 and slot 168, respectively, aligning the hole 176 on the upper extendable moment arm 72 with two of the holes 170 in the attachment nut 68 and aligning the hole 178 on the lower extendable moment arm 70 with two of the holes 170 on the attachment nut 68. A rectangular wave washer 172 having a hole 174 is placed under each of the holes 176, 178 in the respective upper extendable moment arm 72 and lower extendable moment arm 70. Two pins 180 are inserted through the hole 174 of each washer 172, through each hole, 176, 178, through each extendable moment arm 72, 70 while capturing each pin 180 in the corresponding holes 170 of the attachment nut 68. In this embodiment of an attachment nut 68, there are two upper extendable moment arms 72 and two extendable moment arms 70, one of each which are attached on the opposite side of the attachment nut 68 not visible in FIG. 2B. The rectangular washer 172 is shaped and configured to hold the extendable moment arms 70, 72 in place with the overall circumference of the attachment nut 68, but also hold the extendable moment arms 70, 72 extended when desired as required for its functional operation, which will be described later. The rectangular wave washer is not flat and provides a biasing force against the extendable moment arms 70, 72 and the inner portions of the attachment nut 68. While this embodiment of an attachment nut 68 has two upper and two lower extendable moment arms, other embodiments may have fewer, or more, or differently shaped or oriented extendable moment arms. Likewise, alternative shapes and features are possible for other embodiments of the attachment nut 68. Other types of washers or biasing elements may be used to provide a frictional force to hold the extendable moment arms 70, 72 in place, such as triple wave washers, wave washers, spring washers, Belleville washers, disc springs, or combinations thereof

FIG. 2C is an exploded view of a portion of the assembly of the surgical equipment holder dock 10 of FIG. 1, focusing on the combination of the subassemblies illustrated in FIGS. 2A and 2B. Two pins 24 are inserted into holes 90 and 108, respectively, to continue the assembly of the resulting subassembly shown in FIG. 2A. The large coupler ball 38 is placed within the ball recess 144 of the ball cup 128. The coupler rod 40 is passed through the attachment socket recess 156 of the attachment nut 68 and the shaft step 184 of the coupler rod 40 is inserted and fixedly attached to a hole 182 on the large coupler ball 38. A shaft step 186 on the opposite end of the coupler rod 40 is passed through a center hole 188 on the retainer ring 44 and is fixedly attached into a hole 192 on the small coupler ball 42. Once the large coupler ball 38 and the small coupler ball 42 are attached to the coupler rod 40, the attachment nut 68 is attached to the ball cup 128 by engaging the threads 158 with the threads 142 on the ball cup 128 on the inner recess wall 138 of the ball cup 128. Once the threads 158, 142 are engaged, the attachment nut 68 is rotated clockwise to tighten the attachment nut 68 onto the ball cup 128, thereby capturing the large coupler ball 38 between the attachment nut 68 and the ball recess 144 of the ball cup 128. This state of assembly is illustrated in FIG. 2D. When the attachment nut 68 is tightened onto the ball cup 128, the movement of large coupler ball 38 is restricted, and therefore anything attached to the large coupler ball 38, including the coupler rod 40 and any further attachments, are held in place once the attachment nut 68 is tightened on the ball cup 128. The knurls 140 around the top edge of the inner recess wall 138 help provide frictional contact with the large coupler ball 38 to hold the large coupler ball 38 in place. When the attachment nut 68 is loosened from the ball cup 128, the movement of large coupler ball 38 is no longer restricted, and therefore anything attached to the large coupler ball 38, including the coupler rod 40 and any further attachments, are able to move freely in multiple directions. Other embodiments may not include these knurls 140, or teeth to provide frictional forces on the large coupler ball 38. Other embodiments may incorporate textural features on the surface of the coupler ball 38 to enable increased holding forces on the ball.

FIG. 2E is an exploded view of a portion of the assembly of the surgical equipment holder dock 10 of FIG. 1, focusing on the assembly of a side arm. On the base 12 is the side arm mount 84 which has threads 86 that correspond to threads 200 on the end of the shaft of the first side docking arm 46. The first side docking arm 46 is similar in structure to the central docking arm 26, discussed previously, but is simpler in nature in terms of some of its structural features. The first side docking arm 46 has a ball cup 48 towards the upper portion. The ball cup 48 further defines an outer recess wall 204 and an inner recess wall 196. The outer surface of the inner recess wall 196 has threads 194 and there is a socket recess 206 defined by the space between the outer recess wall 204 and the inner recess wall 196. The threads 194 and socket recess 206 are configured for accepting attachment nut 210. The inner recess wall 196 further defines several knurls 198 on the top edge of the inner recess wall 196, configured to aid in gripping a large coupler ball 56, as well as a central ball recess 202. The large coupler ball 56 is placed within the ball recess 202 of the ball cup 48. The coupler rod 58 is passed through the attachment socket recess 218 of the attachment socket 210 and the shaft step 232 of the coupler rod 58 is inserted and fixedly attached into a hole 208 on the large coupler ball 56. A shaft step 234 on the opposite end of the coupler rod 58 is passed through a center hole 236 on the retainer ring 62 and is fixedly attached into a hole 240 on the small coupler ball 60. Once the large coupler ball 56 and the small coupler ball 60 are attached to the coupler rod 58, the attachment socket 210 is attached to the ball cup 48 by engaging the threads 194 on the ball cup 48 with the threads 220, not visible in this view, but similar to the one discussed previously in regard to FIG. 2C on the ball cup 48 on the inner recess wall 196 of the ball cup 48. Once the threads 194 are engaged, the attachment socket 210 is rotated clockwise to tighten the attachment socket 210 onto the ball cup 48, thereby capturing the large coupler ball 56 between the attachment socket 210 and the ball recess 202 of the ball cup 48. When the attachment socket 210 is tightened onto the ball cup 48, the movement of large coupler ball 56 is restricted, and therefore anything attached to the large coupler ball 56, including the coupler rod 58 and any further attachments, are held in place once the attachment socket 210 is tightened on the ball cup 48. The knurls 198 around the top edge of the inner recess wall 196 help provide frictional contact with the large coupler ball 56 to hold the large coupler ball 56 in place. When the attachment socket 210 is loosened from the ball cup 48, the movement of large coupler ball 56 is no longer restricted, and therefore anything attached to the large coupler ball 56 including the coupler rod 58 and any further attachments, are able to move freely in multiple directions.

The attachment socket 210, as previously described, has a generally disc-shaped structure. The top layer 222, mid layer 224, and bottom layer 226 are flat, thin segments defined by the attachment socket 210 that extend outward from the center structure of the attachment socket 210. The attachment socket 210, including the top layer 222, mid layer 224, and bottom layer 226 further define several recesses and protrusions encircling the circumference of the attachment socket 210. These recesses and protrusions form an ergonomic gripping feature on the overall form of the attachment socket 210, which may enable or facilitate hand tightening of the attachment socket 210 by providing gripping features. The spacing between the top layer 222, mid layer 224, and bottom layer 226 define an upper slot 228 and a lower slot 230. The attachment socket 210 also has two upper extendable moment arms 54 and two lower extendable moment arms 52, which are attached to the attachment socket 210 in a similar manner as previously described in regard to the attachment nut 68 in FIG. 2B. While this embodiment of an attachment nut 68 has two upper and two lower extendable moment arms, other embodiments may have fewer, or more, or differently shaped or oriented extendable moment arms. Likewise, alternative shapes and features are possible for other embodiments of the attachment nut 68. While not shown in these views, the assembly of the second docking arm is similar to the assembly of the first side docking arm attachment shown in FIG. 2E.

FIGS. 3A and 3B are top-right-front perspective views of the surgical equipment dock holder of FIG. 1 with two side arms in addition to a central docking arm and three surgical equipment holders mounted on each arm. The surgical equipment holder dock 10 comprises a base 12 which defines a lower clamp jaws 14 and has an upper clamp jaw 16 which is movable and slidably engaged within the base 12. A central docking arm 26 is attached at the top of the base 12. The central docking arm 26 has a locking nut 28 and a body lock knob 30 and attachment nut 32 connected to the central docking arm 26 as described previously in regard to FIG. 1. Releasably held between the body lock knob 30 and the attachment nut 32 is the large coupler ball 38 connected to the coupler rod 40. A small coupler ball 42 and retainer ring 44 attached at the opposite end of the coupler rod 40 are fastened to a central surgical equipment holder arm assembly 242. The central surgical equipment holder arm assembly 242 has a first arm 244 attached to the retainer ring 44, a locking joint 246 which joins the second arm 252 to the first arm 244. A lever block 248 having an operating lever 250 is located at the top of the locking joint 246. The second arm 252 also has an end joint 254 which includes an end effector 256. The end effector 256 is an attachment point for attaching any number of surgical equipment to the end of the central surgical equipment holder arm assembly 242. In this configuration, a piece of surgical equipment, would be easily repositionable by adjusting the central surgical equipment holder arm assembly 242. The operating lever 250 is configured to lock and unlock the joints of the central surgical equipment holder arm assembly 242 at the small coupler ball 42, locking joint 246 and end joint 254, allowing the joint to move freely when unlocked, and holding the small coupler ball 42, locking joint 246, and end joint 254 in a locked position, therefore keeping the relative positions of the first arm 244, second arm 252, and end effector 256 in position.

The base 12 of the surgical equipment holder dock 10 also includes a first side docking arm 46 connected to a side arm attachment nut 50, holding another coupler rod 58 in position. This coupler rod 58 also has a large coupler ball 56 held between the ball cup 48 connected to the first side docking arm 46 and the attachment nut 50. The upper extendable moment arms 54 are shown extended, indicating that that attachment nut 50 is being tightened. This will be further described later. A small coupler ball 42 (not visible here) and retainer ring 62 attached at the opposite end of the coupler rod 40 are fastened to a first side surgical equipment holder arm assembly 258. The first side surgical equipment holder arm assembly 258 has a first arm 260 attached to the retainer ring 62, a locking joint 262 which joins the second arm 268 to the first arm 260. A lever block 264 having an operating lever 266 is located at the top of the locking joint 262. The second arm 268 also has an end joint 270 which includes an end effector 272. The end effector 272 is an attachment point for attaching any number of surgical equipment to the end of the first side surgical equipment holder arm assembly 258. In this configuration, a piece of surgical equipment, would be easily repositionable by adjusting the first side surgical equipment holder arm assembly 258. The operating lever 266 is configured to lock and unlock the joints of the first side surgical equipment holder arm assembly 258 at the small coupler ball 60, locking joint 262 and end joint 270, allowing the joint to move freely when unlocked, and holding the small coupler ball 42, locking joint 246, and end joint 254 in a locked position, therefore keeping the relative positions of the first arm 260, second arm 268, and end effector 272 in position.

The base 12 of the surgical equipment holder dock 10 also includes a second side docking arm 64 connected to a side arm attachment nut 68, holding another coupler rod 76 in position. This coupler rod 76 also has a large coupler ball, not visible here, held between the ball cup 66 connected to the first side docking arm 64 and the attachment nut 68. A small coupler ball 78 and retainer ring 80 attached at the opposite end of the coupler rod 76 are fastened to a second side surgical equipment holder arm assembly 274.

FIG. 8 is a partial cross-sectional view of the surgical equipment holder dock of FIG. 7. FIG. 8 is directed to the knob 518 and central attachment nut 520 portion of the central docking arm 514 portion of the surgical equipment holder dock of FIG. 7. The knob 518 defines an inner circumference having mechanical threading, or threads 620. Also illustrated is the inner rod 512 which is free to rotate within the central docking arm 514. A portion of the inner rod 512 also defines mechanical threading, or threads 622 on an outer circumference of the inner rod 512. When the knob 518 is rotated or turned in direction 624, the threading 522 of the inner rod 512 and the threading 520 of the knob 518 intermesh to drive the inner rod 512 in an upward direction 626. As the inner rod 512 is rotatably coupled to the upper clamp jaw shaft 508 and the upper clamp jaw 506, the upper clamp jaw 506 is therefore pulled upwards in direction 626 as the knob 518 is rotated in direction 624. This rotation as described increases the distance between the upper jaw and the lower clamping jaw, allowing the base 502 portion of the surgical equipment holder dock 500 to be loosened and either removed from a table rail, or the jaws separated to a sufficient extent such that the base 502 portion of the surgical equipment holder dock 500 can be placed onto a rail of an operating table or similar rail. When rotating knob 518 in the opposite direction, the distance between the upper jaw and the lower clamping jaw is decreased. This allows the base 502 portion of the surgical equipment holder dock 500 to be tightened and clamped onto a table rail such that the base 502 portion of the surgical equipment holder dock 500 can be firmly held onto a rail of an operating table or similar rail.

FIGS. 9A and 9B are partial cross-sectional views of the surgical equipment holder dock of FIG. 7. FIG. 9A illustrates the a view of the knob 518 and central attachment nut 520 portion of the central docking arm 514 portion of the surgical equipment holder dock of FIG. 7. As shown in the central attachment nut 520, a retaining assembly 628 is held captive in the central attachment nut 520 and constrains the large coupler ball 532 and the attached coupler rod 534 from being removed from the top of the central attachment nut 520. Surrounding the ball and also held captive in the central attachment nut 520 is an upper crenulation ring 634 which defines several upper interdigitating features 636. These upper interdigitating features 636 are structured as spaced blunted spikes or rectangular, peaked fingers that assist in aligning and interlocking the central attachment nut 520 when fully attached to the ball cup 630 portion of the surgical equipment holder dock 500. The ball cup 630 also includes several lower interdigitating features 632 in the center portion of the ball cup 630. These interdigitating features 632 are structured as spaced blunted spikes or rectangular, peaked fingers that assist in aligning and interlocking the ball cup 630 when the central attachment nut 520 is attached to the ball cup 630. When the central attachment nut 520 is placed onto the ball cup 630 and rotated in direction 638, there are threads 633 defined by the outer wall of the central attachment nut 520 that intermesh with corresponding threads 635 defined by an inner wall of the ball cup 630. As the central attachment nut 520 is tightened onto the ball cup 630, the ball 532, and therefore the attached coupler rod 534 and accompanying surgical equipment holder is at first movable, pivotable, and captive between the central attachment nut 520 and the ball cup 630. As the central attachment nut 520 is tightened further, at times with the assistance of the extended extendable moment arms, the shapes of the upper interdigitating features 636 on the central attachment nut 520 and the interdigitating features 632 on the ball cup 630 are complementary and correspond to one another such that they interlock as the central attachment nut 520 is further tightened onto the ball cup 630. As shown in FIG. 9B, as the central attachment nut 520 moves in direction 640, the rotational force of tightening central attachment nut 520 is translated into vertical tension in direction 640, the large coupler ball 532 and therefore the coupler rod 534 and accompanying surgical equipment holder is held immobile and in a fixed position until such time that the central attachment nut 520 is once again loosened. The interlocked and interdigitating nature of the upper interdigitating features 636 on the central attachment nut 520 and the interdigitating features 632 on the ball cup 630 helps align and preserve position of a surgical equipment holder, and therefore an attached surgical tool or piece of surgical equipment. Maintaining a constant and consistent position of surgical tools and equipment is improved with the use of an attachment feature as described herein. An additional view of this interlocking feature in a fully tightened configuration is illustrated in FIG. 8 as well. While the interdigitating features 632, 636 shown herein have a particular shape and spacing, other possible shapes and spacings known to those skilled in the art may be used in alternate embodiments.
